仰角的内容梗概

假如给我三天光明的英文简介内容~

What would you look at if you had just three days of sight? Helen Keller, blind and deaf from infancy, gives her answer in this remarkable essay.

I have often thought it would be a blessing if each human being were stricken blind and deaf for a few days at some time during his early adult life. Darkness would make him more appreciative of sight, silence would teach him the joys of sound.

Now and then I have tested my seeing friends to discover what they see. Recently I asked a friend, who had just returned from a long walk in the woods, what she had observed. “Nothing in particular,” she replied.

How was it possible, I asked myself, to walk for an hour through the woods and see nothing worthy of note? I who cannot see find hundreds of things to interest me through mere touch. I feel the delicate symmetry of a leaf. I pass my hands lovingly about the smooth skin of a silver birch, or the rough, shaggy bark of a pine. In spring I touch the branches of trees hopefully in search of a bud, the first sign of awakening Nature after the winter’s sleep. Occasionally, if I am very fortunate, I place my hand gently on a small tree and feel the happy quiver of a bird in full song.

At time my heart cries out with longing to see all these things. If I can get so much pleasure from mere touch, how much more beauty must be revealed by sight. And I have imagined what I should most like to see if I were given the use of my eyes, say for just three days.

On the first day, I should want to see the people whose kindness and companionship have made my life worth living. I do not know what it is to see into the heart of a friend through that “window of the soul,” the eye. I can only “see” through my fingertips the outline of a face. I can detect laughter, sorrow, and many other obvious emotions. I know my friends from the feel of their faces.

For instance, can you describe accurately the faces of five different friends? As an experiment, I have questioned husbands about the colour of their wives’ eyes, and often they express embarrassed confusion and admit that they do not know. I should like to see the books which have been read to me, and which have revealed to me the deepest channels of human life. In the afternoon I should take a long walk in the woods and intoxicate my eyes on the beauties of the world of Nature. And I should pray for the glory of a colourful sunset. That night, I should not be able to sleep.

On my second day, I should like to see the pageant of man’s progress, and I should go to the museums. I should try to probe into the soul of man through his art. The things I knew through touch I should now see. The evening of my second day I should spend at a theatre or at the movies.

The following morning, I should again greet the dawn, anxious to discover new delights, new revelations of beauty. Today this third day, I shall spend in the workaday world, amid the haunts of men going about the business of life.

At midnight permanent night would close on me again. Only when darkness had again descended upon me should I realize how much I had left unseen.

I am sure that if you faced the fate of blindness you would use your eyes as never before. Everything you saw will become dear to you. Your eyes will touch and embrace every object that came within your range of vision. Then, at least, you would really see, and a new world of beauty would open itself before you.

I who am blind can give one hint to those who see: Use your eyes as if tomorrow you would be stricken blind. And the same method can be applied to the other senses. Hear the music of voices, the song of a bird, the mighty strains of an orchestra, as if you would be stricken deaf tomorrow. Touch each object as if tomorrow your tactile sense would fail. Smell the perfume of flowers, taste with relish each morsel, as if tomorrow you could never smell and taste again. Make the most of every sense; glory in all the facets of pleasure and beauty, which the world reveals to you through the several means of contact which nature provides. But of all the senses, I am sure that sight must be the most delightful.

北道区15695106058： 北极星的仰角是什么是北极星仰角的定义 - ？
薄雍保欣：[答案] 不同地方看北极星它的仰角都不同,如果你在北极点看,它的仰角就是90度 北极星的高度角(仰角)与当地纬度数恰好相同 仰角:视线在水平线以上时,在视线所在的垂直平面内,视线与水平线所成的角叫做仰角.北极星仰角就是你看北极星时与水...

北道区15695106058： 仰角的概念 - ？
薄雍保欣：[答案] 向上看的视线和水平线的夹角叫仰角

北道区15695106058： 什么叫仰角,俯角当我们测量时,再视线与( )所成的角中()叫仰角,()叫俯角 - ？
薄雍保欣：[答案] 当我们测量时,再视线与( 水平面)所成的角中(夹角)叫仰角,(视线与水平面夹角为俯角)叫俯角

北道区15695106058： 视角、仰角、左右对称的定义 - ？
薄雍保欣： 视角:人眼对物体两端的张角.[观察物体时,从物体两端(上、下或左、右)引出的光线在人眼光心处所成的夹角.] 仰角:视线在水平线以上时,在视线所在的垂直平面内,视线与水平线所成的角叫做仰角. 左右对称:通过主轴只能构成一个对称面,分成彼此对称的两部分.

北道区15695106058： 什么叫做卫星天线的仰角,方位角,极化角 - ？
薄雍保欣： 从接收地点看卫星的方向,按正北(或正南)为参考的角度,叫方位角. 卫星与地平线的夹角叫仰角. 由于卫星参考平面是所在经度的平面(水平面),对于处在不同经度的接收地点,具有一定的夹角(不在与水平面重合),叫做极化角.例如偏西面的卫星,如果是用水平极化波发送,对于处于偏东的接收机,收到的电波就不再是水平的,而是东高西低的倾斜方向.

北道区15695106058： 怎样理解站在山坡上的仰角 - ？
薄雍保欣： 仰角:视线在水平线以上时,在视线所在的垂直平面内,视线与水平线所成的角叫做仰角. 也就是说不管你是处于什么情况下,只要你的视线在水平线以上,在视线所在的垂直平面内,视线与水平线所成的角是仰角 和坡度是没有关系的.

北道区15695106058： 航模术语中的失速仰角是什么意思?？
薄雍保欣： 应该是是迎角不是仰角 迎角指的是机翼参考翼弦线与来流方向的夹角.再通俗点解释:你看机翼差不多就是一个平板么,这个板相对于前面吹过来的风抬起来有多少度,这个就是迎角. 通常来说,迎角越大,机翼产生的升力也就越大,但是迎角的增大是有限度的.当迎角到达失速迎角后,升力不光不会增大,反而会降低.这时的迎角就是失速迎角. 对于航模操纵来说,拉杆拉得越多,飞机的迎角就会越大.如果这个时候你不增大油门而只是单纯拉杆的话,就会看到航模机头会竖起来,但飞机不往上升,这个时候飞机迎角就到达了失速迎角.

北道区15695106058： 在解直角三角形的应用中,仰角和俯角分别是与什么的夹角? - ？
薄雍保欣： 仰角:指的是向上看时,视线与水平线的夹角.俯角:指的是向下看时,视线与水平线的夹角.

北道区15695106058： 经纬仪中的仰角和俯角的判定 - ？
薄雍保欣： 盘左位置:垂直角大于90度小于180度俯角,小于90度大于0度仰角 盘右位置:垂直角大于270度小于360度俯角,小于270度大于180度仰角

北道区15695106058： 什么是仰角,什么是俯角?最好有图. - ？
薄雍保欣：[答案] 仰角就是指人的视线是向上的,人的视线和水平线的夹角 俯角就是指人的视线是向下的,人的视线和水平线的夹角
